" z'o use in bad, the con ointly to rub and presa -Tqallwhomitmyconcermf Be it known that I, Piunir Piu'rr, a citizen of the United States,residing at Boston,'i n the county of Suffolk and State of 6Mnasachusetts,'l have invented 'certain new and useful Im rovements inMachines for Impregnating abrics, of which the followin is aspecification.

This invention haa for iteobject to ro- 10 videa machine forimpregnating textilel abric, auch as cotton duck or canvas, with a`composition intended to adapt the fabric for certain uaea auch as themanufacture of automobil'e tires, driving belts, etc.

i5 My vention has particular reference. to ythe impregnation of fabricwith a solution of unvulcanized rubber commonly known as rubber cementfor the purpose of'frictioning the fabric and thus adapting itfor the'manufacture of various articles of which 4frictioned lfabric forms apart. My aim ia to force the frictioning composi- .tion ao thoroiifhiyinto the fabric that all partlof it wi be permeated by the compo- "zs,new, o im .u the aber of the Ammc l lwill be intimately united, and thesurfaces of the fabric will be intimately united to the like aurfacaawith which theyara in con when the. fabric haa been subjected ,to hea 80to vulcanixe the rubber solution.

' M51 invention is embodied in a machine whi includes 'a' reservoiradagited tccontain acompoaltion auch aa ru .ber cement, q meansforguiding a web or stripl of fabric It -througb the'reservoir, a bedwithin the reservoir in contada with the moving fabric, and a prenuremember which is to prem the fabric against the bed and is adapted to beAreciprocated in contact with 4o the fabric inter between it ands the anvthe pressure member act the compoaition oroughly into the meshes andfibers of fabric. The invention is also em- 45 bodied in various otherfeatures incidental to the general purposes above stated, said featuresincluding means for drying and heating the fabric before it enters thereservoir, and means for d'ryin the ini nated tu fabric after it hnspassetigthrougi t e reservoir.

The bed 18 may be of any desired form und is preferably of segmentalform, as

shown by Figs. 1 and 5, and is rigidly supported in any suitable way y.vithin the reservoir, preferably by means of a frame 16 to which thebed is attached, said fr'ame having ears 17 bolted to the side members18 of the supportii frame of the machine. The pressure mem r 14 which isin all cases re ciprocated in a path is p A ferabl carried by a pair oflevers which 10 are. o at 19, each lever including a .piro I iodyportion 20, and a portion ,21, which ia' mova le in aJguide or socket 22on l thebody pprtion and is provided with hear imm! ig. 5) in' which theshaft of the pressure member 14 is journalcd. The portions 21- ofthelevers are controlled by springs 2 4 which act to press the member 14yieldingl toward the bed 13. The levers 2Q .are oscil ated b means ofeccentrics 25, 3o allixcd to a driving shaft 26, stra sl 27 surrounding.said eccentrica, and r 28 connecting said straps with the.i ipper endsof the1evers20. .i

I refer to provide two beds and pressure a5 mem rs, one located' in theupper andthe other in the lower portion-of the reservoir. The upper bed'18, and the correa nding rassure member 14 are decori above. ie lowerbed 18- is also segmental and is o supported by frame pieces 16l whichma be bo ted tothe aides of the reservoir. he ressureniembcrfaccoinpanying the lower d is, as here shown, com d ofa pair oflon itudinal corrugated i le rolls 14,z 14', anjourna ed in bearings20.- These beurin.

The levers carrying the lower 'l pressuremembers are connected with. the.

evers. carrying the upper pressure members bv links 82, which transmitmotion from Il theupper to the lower levers, the upper and lowerpressure membersv being i therefore moved simultaneously in oppositedirections. The pivotal connection of the bearings 29 to the levers,enables said bearings to rock and sa equalize pressure on the-grolls14", 14,.

against the fabric interposed between them and'thebed 18. i y

It will now be eeen that provision is made for forcing the compositionsimultaneously M5 'into two portions of the fabric, one of said parallelwith the bed portions being at the lowcrfpert and the other at the upperpart of the reservoir. The composition in the lower part of thereservoir having greater density than that in the upper part, probablypenetrates the fabric more deeply ilmu the composition at the upperpoi-tion of the tiink.

38 represents a stirring blade or agitator which is movable with thelower pressure member and is adapted to prevent sedimentation in thereservoir, the blade bein 'preferabl perforated, as shown by Fig. Ashere iown, the. bladettl is attached to a sleeve 84 mounted on a rod 35which is atlixed to the ears 86 depending from the bearings 29.

'The fabric 15 is guided into the tank between feed rolls 37 (Figs. 1and 0) one of which is driven by a sprocket chain 38 from a sprocketwheel on the driving shaftl 26. Within the reservoir are a series ofgpide rolls 89, arranged to guide the fabric in a series ofsubstantially horizontal stretches, the fabric passing from the feedrolls 37 to the lowest guide roll 89 and from thence upwardiy over theintermediate guide rolls.

As shown by Fig. 1, the fabric passes from the up r guide roll 39 over aideroll 40 to the 18, and under a i e roll 41 be tween feed rolls 42 and43 w icliare located above the reservoir; the* feedroll 42. beiglen'redto and driven by the driving shaft 2 he ifabric .'is thus mov'cdprogressively through the tank, one of thelower stretches of the fabricpassing between the 'lower bed 13* and the corresponding pressuremember, whilethe u per stretch of fabric between the guide ro le and 41,passes between the upper bed 18 and thecorresponding preasure member 14.i 4The fabric before treatment is wound on a l delivering roll '44 whichis journaled in bear in in a freine at one endiof the machine, thefabric passing from the. roll -44 in contact with the .guide rolls 45and,46,to"a

lpreliminary drier which heats and dries the abric 'and delivers it in aheated condition to the reservoir. The said drier, which is shown insection by Figs. 7 and V8, includes, two chambers- A47 48, each ada vtodto be I heated internally by steam or'o er heati medium. .Said cham rsare preferably o angular form in cross tion, as shown by Fig. 7, and'are separated from eii'ch other'by a narrow passage 49 through which thefub- I ric passes, the oppoged aides of the chambers being in closeproximity to the fahne interposed between the'chambe'rs. The chamber 48is preferably provided with flanges'tO (Fig. 8) which bear on thechamber 471aiid 1 form the edges of the passage 40. l re ircscnts o.suction boit,` which is included iii the structure of the chamber 47,-the latter' being sub-divided as shown by Figs.l 7 und 8, to form thesuction box 'be l tween two heated portions of the chamber 47. ln thetop of the suction box is a narrow slot 52 extending crosswiae of thopassage 49. I

53, 53 represent suction pipes which are connected with a suitableair-exhausting aparatiis, not shown, acting to exhaust air 1s tranceinto t e tank in a dry and hot condition. The tlan close the passage 49at its opposite ges so that air can enter the passage 49 only at itseHiposite ends and hasta pass over t e heat surfaces of the soclis'mbers before passingthrough the slot 52. Thel means here shown forcirculating the heating medium thrcu the, chambers 47,

The chambers 47 and 48 are so arranged so that the delivering end of thepassage 49 is -above and in close proximity to t e feed l rolls 37, thefabric passing from the passage 49 over a guide roll 57 to the feed rols B7.

The fabric is kept under suitable tension 85 between the sup ly rolls 44and the feed rolls 87 by a friction rake 58 (Fig. 1 applied to theperiphery of-the roll 44 an controlled by a` weight 59.

The impregnated fabric passes from the i 4o feed rolls 42 and 43 througha seconda? drier, shown in elevation by Figs. 2 and Said drier comprisesa fiame 60-having supports for a.phirality of manifold steam pipes 62,each series of manifolds being hori- 48 zontally arranged to form o nheating shelves, and the manifolds being suitably connected so thatsteam continuously throu the entire series. 'A casing 63 surroun s theframe and the heating manifolds, e0 said casi beingbopreferably rovidedwith inlets 64 n the ttom, for hs admission Iof air. Journaled inbearing( at lthe end p0rtions of the frame are guide rolls 6 5, arlranged to conduct the fabric in scenes of e6 substantially parallelstretches betweenthe manifolds 62. The guide rolls 6 5 are positivelydriven from a shaft 66 supporting one of said rolia, by sprocket chains67 engaged with a s rocket wheel on the shaft 66 l0 and correspon ingsprocket wheels on the rolls 65, the shaft 66 being driven from theinain driving shaft .26 throu h a sprocket chain 68 e 'with.sp et wheelsaffixed to the sa d shafts. The fabric passes el from the feed rolls42,- 48, to the lower guide roll through an opening 60 in the easing 63,the course of the fabric through thiseeondary drier being clearlyindicated h'v Figs. 2 and 3. The impregnating composition is thoroughlydried during the passage of the 70 fabric through thc secondary drier,the fabric einer ngfrom the casing 63 through an opening i0, (Fili. 3) lThe dried fu ric is accumulated on n winding roll 71 (Fig. 3), thetruiiiiioiis of l5 which are journalod in bearings or swinging arms 72,pivotcd at 7J,` to a frame 74 located adjacent to the delivering end ofthe secondary drier. v

75 represents a druiii which is driven b'y 80 a sproc et chain .l enaged with a sprocket wheel on one of the `riven guide rolls 65. Theaccumulation of fabric on the winding roll 71 is in frictional contactwith the drum 75 and is rotated therefore in the direction I5 reiuiredto accumulate it on the winding rol 71. As the accumulation increases,the winding roll rises, the arm 72 swinging up wardly. l

76 represents a i-oll on which is wound an 90 accumu ation of pai'allinpaper 77 or other material adapted to be interposed between theconvolutions of the impregnated fabric on the' winding roll 71 toprevent said convolut-ions adhering to each other. The paper 77 passeswit i the impregnated fabric 15 to the winding roll 71 and is woundtherewith, the convolutions of the fabric and paper alternating. Tensionis maintained on the paper 77 by a friction brake 7 8 bear- 100 ing onthe pcriphery of the roll 76 and controlled by t e weight 79,

The machine may be provided with corrugating rolls 80 and 81, as shownby Figs. 9 and 11, for forming transverse corruga- 105 tions in theimpregnated fabric after it leaves the rolls 42 and 43. Said corrugatingrolls 80 and 81 are arranged to act on the strip in close proximity tothe rolls 42 and 43. The lower corru ated roll 81 has a.' 110 ar 82(Fig. 11) wliic is eonnected'by an intermediate ar 83 with a ar 42" ontheshaft 42l of t e roll 42, sai gear 42" also meshing 'with gear 48" onthe shaft 43 of the upper roll 43.

The u per corrugatedA roll 80 has a sutilcient in ermoshing eggailamentwith the lower corrugated roll t rough the interposed strip to reuse itsrotation. The strip. is in a relatively sti' condition when it cn- 120counters the corrugating rolls so that the corrugations imparted to itare adapted to withstand the pressure to which the strip is subjectedduring the remainder of its course through the machine. Although thecorrugations may be somewhat flattened by said pressure," they aresulliciently ro nounced when the strip is finally woun on thc roll 76,to accomplish the result desired, which is to prepare the fabric for.the subla.)
